To aZZ'wwm t may concern.'

Be it known that we, Josnri-i IV. Si-mnr, Jr., and ALBERT E. BACON, citizens of the United States, residents, respectively, oil Berwyn, county et' Chester, State ot Pennsylvania, and Germantown, county of lhiladelphia, State of Pennsylvania, have invented a new and useful Flushing Device, oi" which the following is a specification.

ur invention relates to improvements-in automatic flushing devices for water closets. rlhe object is to provide an improved seltcontaining means for automatically flushing the closet. Our invention includes improved means for conveniently securing the flushing device to a standard earthenware closet without requiring any changes in the construction of said closet, and so that all the parts of the flushing device shall be entirely outside of the bowl of the closet.

Our flushing device is adapted to be secured to the earthenware closet so that the closet shall support the same to properly withstand the thrust and pressure of operating the valve and also the pressure of the water. Our device is adapted to be located out of the way and yet readily accessible for inspection or repair, and also readily removed. Our device is adapted to be operated with certainty in connection with the operation of the seat.

Our invention also comprises improvements in details of construction. y Referring to the drawings Figure 1 is a plan view of our device with part shown in section.

Fig. 2 is a side elevation on a smaller scale. f

Fig. 3 is a vertical section on line 3--3 of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

In Figs. 1, 2 and 3, we show a device adapted to be secured to a closet having an inlet opening in the top of the bowl. A convenient way of securing our device to the closet is to provide the extension 9 of body 7, which corresponds to the spud, with a threaded end, and a coperating threaded ring 8, a collar 10 and a rubber gasket 11. The gasket 11 is inserted in the opening of the closet and the threaded ring 8 is then moved toward ring 10 causing a compression thickens the gasket, in a Well known Way,

for engagement with pipe 13 leading to tankl 40, and a horizontally extending nozzle 14 for engagement with the supply pipe l5. The body structure 7 is provided with three chambers as follows: chamber 16 connected with the closet, chamber 17 connected with the tank and inlet chamber 18 connected with the supply. T he partition 19 separating chambers 16 and 17 is apertured and provided with a valve seat 20 having a cooperating valve 21. The partition 22, separating chamber 17 from 1S, is apertured and is provided with a valve seat 23 having a cooperating valve 24. Valve 21 is normally held in the open position by the spring 25, while valve 24 is normally held in closed position by the compression spring 26. Connected with the valve 21 is the slide rod 27 which projects through a suitable packing 2S beyond the body member 7, and preferably carries at its free end an anti-friction ball device 29 for engagement with a contact plate 30 located on the back of the seat 31. `This friction ball device 29 is secured within the hollow casing 34 adjustably mounted on the end of rod 27 of which it forms a part and secured in place by set screw 35. The necessary movement of rod 27 to secure the required actuation of valves 21 and 24, and to take up wear, is thus secured. Secured to slide rod 27 and projecting in front of valve 21 is the rod 32 which is adapted to engage and project into a socket of valve member 24.

The chambered extension or lug 84 of body member 7 is provided with the upwardly directed apertured lug 34. Supported above the bowl by the apertured standards 86 is the rod 36 forming a strut or brace for the hinges 37, which, with standards 86, are secured thereto by pins 87. This construction permits the rotation of strut 36 in a horizontal plane, the axis of which passes through the apertures in hinges 37. The bolt or brace 35 passes through strut 36 and lug 34. l/Vhen the required position of adjustinent between brace 36 and body 7 is secured bolt 35 is secured in position by nuts 38 and 39, thus maintaining the parts in said position of adjustment and clamping brace 3b against movement upon the elevation or (flepression of the seat.

It should also be noted that the connections between body 7 and pipe 13, and supply pipe 15 are made with threaded coupling rings and ground joints so that they can be readily disconnected when it is desired to take the valve structure apart. By unscrewing the cap G5 valve 21 may be removed. 1t might also be noted that the spring is confined between a washer l1 which engages with the slight annular projection 112 in the inside of body member 7, and with the ring or 4ilange 113 at the other end, which may be integral with rod 27. On the other side or ring from the spring may also be provided a `washer or' some soit material 4&1-, for taking the jar of impact between ring L13 and plug (55, as the spring 25 normally holds this ring against the inner end oi plug (55. The spring 26 controlling valve 24 is eonlined between the iiiange L15 of valve member 2-1 and the ea p 11G which is threaded onto the end or the body portion 7. It will thus be seen that by removing plug and cap L16 the two valves can be instantly removed for inspection or repair. By disconnecting the coupling rings 17 and 18, nut 39, and loosening ring 8, the entire valve structure can be removed.

The operation of the device is as follows:

Referring to Fig. 3, the several valves are held in position against the pressure exerted by springs 25 and 26 by seat member 31 when held down in the horizontal or operative position. lll/hen the seat member 31, is moved into the horizontal position the contact plate 30 presses against the anti-friction bearing 29 and forces the slide rod 27 in or to the right hand, closing the valve 21 onto valve seat 20. 'This movement oi' the slide rod 27 also lorces the rod 32 and valve 241 with which it engages, into the open position. 1n these positions of the valves the water from a suitable source of supply under pressure, enters through pipe 15 and chamber 18, into chamber 17, and passes through pipe 13 to tank 10,lling said tank l.l0 until the same is under-the same pressure of water as that of the source of supply. Upon removing the weight from seat 31, the seat moves to the position shown in dotted lines in said Fig. 3, or in solid lines in Fig. 2, in response to the pressure exerted by the rod 27 Aactuated by spring 25. This 55 movement oi' rod 27 in the left hand direction carries the valve 21 into open position and also permits the closure of valve 2li in response to actuation of spring 26. When valve 24; is closed the pressure of water from 60 the source of supply cooperates with the pressure of spring 26 to maintain said valve 24 in the closed position. Valve 21 now being open, the water flows from tank l() into chamber 17 thence to chamber' 16, through 65 spud 9, to the water closet, until the tank is empty. Upon closing the seat again the operation is repeated.

What we claim is 1. lin combination with a water closet bowl and a hinged seat, hinge posts adapted to maintain the hinge axis at a point a substantial distance above the horizontal plane of the seat, a chambered body having water inlet and discharge apertures and a valve- 7,-,

controlled port therebetween, a spring-actuated seat actuating valve-controlling rod projecting :from the chambered body, above the top of the bowl, and a strut engaged between the hinge posts and the chambered body, as and for the purpose specified.

2. 1n combination with a water closet bowl and a hinged seat, hinge posts supported on the bowl structure, said posts adapted to maintain the hinge axis above the horizontal plane of the seat, a chambered body outside the bowl structure, said body having water inlet and discharwge apertures and a valvecontrolled port therebetween, a spring-controlled valve and seat actuating rod project- JOSEPH W.
